我有主页 index.xhtml ，其中声明了放置内容的位置取决于单击的页面。
<br>
<div id="centerContent">
<ui:insert name="centerContent" >
<ui:param name="mainTag" value="" />
<ui:include src="/template/commonContent.xhtml" />
</ui:insert>
<h4>#{mainTag}</h4>
</div>
</br><br></br>
<p:panel id="content">
<h:form>
<h:inputText id="namez" ></h:inputText>
</h:form>
</p:panel>
</p:layoutUnit>
我的模板 commonContent 是：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
>
<body>
<ui:composition>
<h1>Ubezpieczamy najlepiej!</h1>
</ui:composition>
</body>
</html>
发送电子邮件的页面是：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
>
<h:body>
<ui:composition template="index.xhtml">
<ui:define name="centerContent">
<h2>Zapytaj</h2>
<h:commandButton actionListener="#{mySendBean.sendMail2()}" value="Welcome Me">
</h:commandButton>
<ui:param name="mainTag" value="Z chęcią odpowiemy" />
</ui:define>
</ui:composition>
</h:body>
当 commandButton 放在主页上时它可以工作，发送电子邮件，但是当通过模板加载时它不起作用。万事俱备，但不是<h:commandButton actionListener="#{mySendBean.sendMail2()}" value="Welcome Me">。为什么通过单击的模板加载时它不起作用？
